Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.
It depends (IS) the frequency of the waves.
Ripple.
Count the number of waves passing a point in one second. That is frequency. Or count waves for 10 seconds and divide by 10.
It depends on the objects, how far apart they are and whether or not one can be seen from the other. If they are moderately far apart, echo location (sonar or radar) located at one of the objects can be used. A beam of radio or sound waves is aimed at the object and the time taken to receive an echo is measured. Since the speed of radio waves or sound waves in the relevant medium is known, the distance travelled by these waves can be calculated. The distance to the object is then half the calculated distance (the waves have to go there and come back).
Comparison of waves going through the solid inner core and those just skimming it can show the rotation of the inner core.
because the surface of water is horizontal and not vertical.........................
Simple answer:When a stone is thrown into quiet water, the circular waves that are formed are transverse waves. We say the waves are circular because the shape of the wave front is circular and we say it is transverse because the surface disturbance is vertical, perpendicular plane of the surface in which the wave moves.The waves have both properties of being circular and transverse.More Explanation:Transverse waves are waves where the direction of the oscillatory motion is perpendicular to the direction of propagation of the wave.The waves on the surface of water are a vertical motion of the water.The waves on the surface move on the surface, which is horizontal, so the propagation is in the horizontal direction.Horizontal is perpendicular to vertical, so circular water waves as well as linear water waves are transverse. Indeed, no matter what peculiar shape you produce, the water disturbance is vertical and the motion of propagation is restricted to the horizontal surface.

It blocks the waves vibrating on a vertical plane
Surface waves (e.g. Rayleigh waves, Love waves) that produce vertical motion of the ground surface produce the most damage during an earthquake.
Light acts like both a particle and a wave. These particle-waves are oriented in random directions. Polarisation filters basically filter out the randomly oriented waves, and ensure that only light that is 'polarized' in a certain direction can pass through.Horizontal polarisation is when the light waves are oriented horizontally, and vertical is when the waves are vertical. The same princaple applies to the whole EM spectrum.
Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.
polarization of wave means to allow in one particular direction either it may be a horizontal or vertical and block other direction

A seismograph is the output of a seismometer. Seismometers can be oriented to measure vertical, north-south, and east-west motion (or anything in-between if it were so desired). Some modern seismometers include three instruments in a single unit for this purpose.
